CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of U.S. Provisional Patent Application Serial No. 60/338,664, filed Dec. 11, 2001.

BACKGROUND OF THE INVENTION

[0002] 1. FIELD OF THE INVENTION

[0003] The present invention relates to garage ventilators. More particularly, the present invention relates to louvered ventilators which fit within a standard garage door panel.

[0004] 2. DESCRIPTION OF RELATED ART

[0005] Ventilators for incorporation into garage doors are known. Many of them are mere screens and offer little security and no adjustability as to the degree of ventilation. These screen devices may have a separately installed inner backing plate to shut off the ventilation, or may fold up against solid panels of the garage door. Some must be entirely removed from the garage door when ventilation is not desired, such as in winter. Most present screen devices offer little resistance to forcible intrusion. It would be desirable to provide a garage ventilator which is rugged in construction to foil forcible intrusion, is adjustable between an open and a closed position for selective ventilation, and incorporates a screen for denying entrance of insects into the garage when in an open position.

[0006] U.S. Pat. No. 4,378,043, issued Mar. 29, 1983, to Sorenson describes a garage ventilator having a screen panel pivotally secured to the bottom of a sectional garage door.

[0007] U.S. Pat. No. 4,770,087, issued Sep. 13, 1988 to Danley et al. describes a garage ventilator for fitting in a standard garage door panel which features fixed louvers and a backup screen for preventing entry of insects. The ventilator has a backup panel for closing off the ventilator when ventilation is not needed.

[0008] U.S. Pat. No. 4,323,104, issued Apr. 6, 1982, to Guttman describes an openable and closeable louvered panel operated by a crank for a door or window opening. No screen is provided for keeping out insects when the louvers are open.

[0009] None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0022] The present invention is a ventilator for installation in a garage door. It preferably fits in place of a standard garage door panel or into the panel. The ventilator includes a frame fitting into the door in place of a panel. The ventilator has openable and closeable louver slats exposed to the outside of the door and operated by a crank located on the inside of the door for adjustment of the louver slats to the desired position. A screen of appropriate mesh is installed on the frame on the inside of the garage, covering the inside such that insects may not enter the garage when the louver slats of the ventilator are open.

[0023] Referring to FIG. 1. there is shown an environmental view of the inventive ventilator. House H has attached garage G with overhead garage door GD having standard panels P. One or more inventive ventilators V are fit in place of standard panels P in order to provide ventilation to the inside of garage G when desired.

[0024] Referring to FIG. 2, there is shown a rear view of the ventilator 10 in a closed position as seen from the inside of the garage G comprising an outer frame 12 supporting louver slats 16 which are subject to opening and closing by the action of crank 20 acting on gears(not shown) in casing 20 mounted on frame 12. Screen 22 is mounted on the rear of outer frame 12 and is of such mesh size as to prevent insects from entering the interior of the garage through the open ventilator. The ventilator is preferably made of aluminum or other metal and is of sufficiently robust in construction as to deter forcible intrusion, particularly when in a closed position.

[0025] Referring to FIG. 3, there is shown a partial sectional side view of the ventilator 10 in an open position wherein frame 12 supports inner screen 22. Louver slats 16 are supported for rotation by slat supports 24 on pivot upright 26 by means of pivot bearing 28 and pivoting is actuated by vertical movement of slat actuating upright 30 by means of actuating bearing 32. Vertical movement of slat actuating upright 30 is effected by means of turning ventilator crank 18 which acts on gears such as rack and pinion gears(not shown) or the equivalent in a known manner.

[0026] In operation, crank 20 is turned by the user in one direction to pull slat actuating upright downward, thus pivoting louver slats 16 to an open position as shown in FIG. 3. Crank 20 is turned in the opposite direction to pivot louver slats 16 to an intermediate position or a closed position as shown in FIG. 2.
